  • Publication number: 20210067045
    Abstract: A three-level modulation for an isolated multilevel DC/DC resonant converter offers output voltage regulation capability with fixed switching frequency and achieves high efficiency along with soft-switching of the power switches. The three-level modulation enables current balance in all power devices, therefore, realizes better thermal performance and longer circuit life. An efficient control method that combines the three-level modulation with conventional frequency modulation achieves a wide output voltage range with a narrow switching frequency range. At any given time, a control circuit selects one of two different modulation schemes to operate the primary-side switches of the resonant converter based on an output voltage, or to one or more external control signals. Together with a selected device switching frequency and duty cycles, the two modulation schemes generate different voltage waveforms to a primary-side transformer, which are coupled to the secondary-side to provide different output voltages.
